Thanks everyone, I got the gun disassembled, cleaned, oiled, and reassembled. The reason for the slide
Being stuck was I turned the barrel trying to remove the slide initially. So I just grabbed the barrel while agitating the slide and it came right off. Thanks for everyone's help
And insight.

I own a R51 now and am experiencing a stuck slide during disassembly and am looking for assistance, it's jammed halfway so I can see into the chamber and about an inch of the barrel, but it will not go forward or backwards period. What should I do or any advice to remedy this situation? Thanks for the help.

Good Day to All,
Tyler here, I'm a new gun owner and first time pistol owner. I'm here just trying to learn a few things or as much as I can from the vast experience and interactions shared on this forum. Thank you so much for the add.
